[0002] High-friction brake shoes are a crucial component and core consumable in railway freight car braking systems, and their quality significantly impacts the safe operation of railway freight transport. High-friction brake shoes are typically manufactured from over ten raw materials that are thoroughly mixed and weighed, then undergo multiple processes including pressure molding and high-temperature curing. During production, the required weight of raw materials for each brake shoe must be manually weighed (generally with an accuracy within ±15g), and the materials are quantitatively packaged. After packaging, the materials are manually moved to the next workstation.

[0020] The invention will now be further described with reference to the accompanying drawings.

[0021] It should be noted that the intelligent packaging system for brake shoe raw materials in this invention is mainly used for packaging high-friction brake shoe raw materials, but it is not limited to this and can also be used for packaging low-friction brake shoe raw materials.

[0022] Example 1 like Figure 1 As shown, this invention provides an intelligent packaging system for brake shoe raw materials. The system includes a raw material pallet module 10, a robot transport module 20, a quantitative packaging module, a material box pallet 40, and a material box pallet conveying module 50. The raw material pallet module 10 is used to store raw materials; the robot transport module 20 is spaced apart from the raw material pallet module 10; the quantitative packaging module is spaced apart from the robot transport module 20; the material box pallet 40 is correspondingly positioned to the quantitative packaging module; and the material box pallet conveying module 50 has the material box pallet 40 mounted on it. The robot transport module 20 can transfer the raw materials stored on the raw material pallet module 10 to the quantitative packaging module. The quantitative packaging module is used to quantitatively distribute the raw materials to the material box pallet 40. The material box pallet conveying module 50 is used to convey the material box pallet 40 to the position corresponding to the quantitative packaging module, or to remove the material box pallet 40 from the position corresponding to the quantitative packaging module.

[0023] The above setup includes a quantitative dispensing module that quantitatively distributes raw materials onto the material box tray 40. A material box tray conveying module 50 transports the material box tray 40 to the next process position. A robot transfer module 20 transfers the raw materials stored on the raw material tray module 10 to the quantitative dispensing module. By integrating the quantitative dispensing module, the material box tray conveying module 50, and the robot transfer module 20, the level of automation in brake shoe production is improved, thus meeting the requirements for automated and mass production of brake shoes.

[0024] Specifically, such as Figure 1As shown, in one embodiment, the raw material pallet module 10 includes a raw material pallet 11, a pallet transfer frame 12, and a pallet transfer frame positioning device 13. The raw material pallet 11 is used to store raw materials; the pallet transfer frame 12 is used to place the raw material pallet 11; the pallet transfer frame positioning device 13 is used to position the pallet transfer frame 12; the robot transfer module 20 is capable of removing the raw material pallet 11 from the pallet transfer frame 12 or placing the raw material pallet 11 inside the pallet transfer frame 12.

[0025] Specifically, such as Figures 1 to 4 As shown, in one embodiment, the bottom end of the pallet transfer frame 12 is provided with a plurality of positioning blocks, and the pallet transfer frame positioning device 13 includes a plurality of positioning blocks 131 fixed on the ground. The positioning blocks 131 are provided with positioning holes, and the plurality of positioning blocks are correspondingly arranged in the plurality of positioning holes, and the positioning blocks are adapted to the corresponding positioning holes.

[0026] Specifically, such as Figure 5 As shown, in one embodiment, the robot transport module 20 includes an industrial robot arm 21 and a transfer device 22, which is connected to the industrial robot arm 21; the industrial robot arm 21 is used to move the transfer device 22, and the transfer device 22 is used to connect to the raw material pallet 11 to transfer the raw materials on the raw material pallet 11.

[0027] Specifically, such as Figure 5 As shown, in one embodiment, the transfer device 22 includes a gripper 221 and a dust baffle 222. The gripper 221 is plugged into the raw material tray 11 and connected to the industrial robot 21. The dust baffle 222 is disposed on the gripper 221 and is used to block the feeding port of the quantitative dispensing module.

[0028] Specifically, such as Figure 1 As shown, in one embodiment, the quantitative dispensing module includes a storage box 31 and a dispensing device 32, wherein the storage box 31 is used to store raw materials; and the dispensing device 32 is used to quantitatively dispense the raw materials in the storage box 31 onto the box tray 40.

[0029] Specifically, such as Figure 6 As shown, in one embodiment, the bottom of the dispensing device 32 is provided with multiple dispensing outlets, and the material box tray 40 is provided with multiple raw material boxes 41, with the multiple dispensing outlets corresponding to the multiple raw material boxes 41 one by one.

[0030] Specifically, such as Figure 6 As shown, in one embodiment, the material box tray 40 includes a tray 42 and a support structure 43. The tray 42 is provided with a raw material box 41; the support structure 43 is provided with the tray 42.

[0031] Specifically, in one embodiment, the intelligent raw material dispensing system for brake shoes further includes a control device. The control device is electrically connected to at least one of the robot transport module 20, the quantitative dispensing module, and the material box tray conveying module 50. The control device can control the robot transport module 20 to transfer the raw materials stored on the raw material tray module 10 to the quantitative dispensing module, and / or control the quantitative dispensing module to quantitatively distribute the raw materials to the material box tray 40, and / or control the material box tray conveying module 50 to convey the material box tray 40.

[0032] The following is combined with Figures 1 to 7 Let me describe a more specific embodiment of this example: This implementation provides a set of intelligent packaging system for brake shoe raw materials, which consists of a quantitative packaging module, a material box pallet conveying module 50, a robot transfer module 20 and a raw material pallet module 10, and is equipped with a PLC control system (control device).

[0033] Specifically, the raw material pallet module 10 consists of a raw material pallet 11, a pallet transfer frame 12, and a pallet transfer frame positioning device 13. The raw material pallet 11 is constructed from welded steel. Each raw material pallet 11 can hold 30 kg of raw material. The three square tubes on the raw material pallet 11 serve as the pallet frame support structure and also as the interface for robot module insertion and handling.

[0034] Specifically, each pallet transfer frame 12 can hold seventeen raw material pallets. Due to the large weight of the raw material pallets, no separate docking structure is required, which ensures the stability of the pallets within the transfer frame. The pallet transfer frame 12 is connected to the transfer frame positioning device through four semi-circular structures at the bottom, which also completes the alignment of the pallet transfer frame, facilitating the robot's handling module to grasp them. Specifically, the pallet transfer rack positioning device 13 is directly installed on the ground and has a proximity switch as a detection mechanism. Once the pallet transfer rack 12 is in place, the control system can detect it and perform the corresponding operation.

[0035] It should be noted that the number of raw material pallet modules can be set by the user to achieve uninterrupted operation.

[0036] Specifically, the robot transport module 20 consists of a 180 kg six-axis industrial robot (industrial manipulator 21) and a transfer device 22, with the robot fixedly mounted on the base. The transfer device is a structure consisting of a three-pronged gripper and a dust baffle.

[0037] During operation, the robot inserts its three-pronged gripper (gripper 221) into the raw material tray 11, directly lifting the tray 11 and horizontally pulling it out. The robot then lifts the tray 11 horizontally to the height of the storage box 31 of the quantitative dispensing module. The control device opens the dustproof opening of the storage box, and the robot inserts the tray into the storage box. The robot then rotates its 6 axes to pour the raw materials into the storage box. During this process, the dust baffle remains stationary to prevent dust from overflowing. After the tray is reset, it exits the storage box, the dustproof opening of the storage box is closed, and the robot's transfer module 20 inserts the raw material tray 11 back into its original position, thus completing one workflow.

[0038] Specifically, the quantitative dispensing module consists of a storage box 31 and a dispensing device 32. The storage box 31 is made of stainless steel and is welded from a frame and a stainless steel plate. It has a dustproof opening that opens and closes pneumatically and has a material dispensing partition inside to make the raw materials falling from above as even as possible.

[0039] Specifically, the storage box 31 is designed with six quantitative dispensing outlets 321 below. The principle is an electromagnetic vibration-assisted quantitative pump structure. Each dispensing port is equipped with a separate quantitative dispensing pump to independently complete the weighing. The electromagnetic vibration assists to promote the flow of powder and improve the dispensing efficiency. The control device will only control the material box tray conveying module 50 to move and move the material box tray 40 to the next position after receiving the signal that all six dispensing is completed.

[0040] Specifically, the material box pallet conveying module 50 is located below the quantitative dispensing module. A support structure is set on the side of the pallet. Positioning devices and lifting mechanisms 51 are set on the material positions of the double-speed chain. During movement, the support structure is placed on the double-speed chain, and the transfer position is controlled by a servo system.

[0041] Specifically, the material box pallet 40 has 6 rows totaling 36 pieces, with support structures on both sides for placement. The pallets are placed onto the conveyor device via an AGV or forklift. A guiding mechanism on the conveyor belt controls pallet centering. When a pallet moves to a certain position, it touches a laser beam sensor to stop, ensuring the pallet's empty space aligns with the hole in the dispensing mechanism. A lifting mechanism 51 raises the pallet position, ensuring a seamless connection between the dispensing device and the material box, reducing dust. After dispensing, the pallet can be directly transferred to the next processing position by an AGV or forklift.

[0042] Example 2 Example 2 differs from Example 1 in the following ways: Specifically, such as Figure 8In one embodiment, the transfer device 22 includes two telescopic rods 223, a bidirectional sliding cylinder 224, a connecting rod 225, a polarization mechanism 226, and a monitoring device 227. The two telescopic rods 223 are plugged into the raw material tray 11; the bidirectional sliding cylinder 224 is connected to the two telescopic rods 223; the connecting rod 225 is disposed on the bidirectional sliding cylinder 224 for connecting the industrial robot 21; the polarization mechanism 226 is disposed on the connecting rod 225 for applying vibration force to the bidirectional sliding cylinder 224; and the monitoring device 227 is disposed on the connecting rod 225 for monitoring the pitch angle and roll angle of the raw material tray 11.

[0043] Specifically, the robotic gripper (transfer device 22) adopts a telescopic rod structure with independent control on both sides. A servo motor drives a precision lead screw to achieve lateral opening and closing and longitudinal extension of the gripper arm. The extension stroke can be adaptively adjusted according to the size of the pallet to be gripped, supporting pallets with a maximum width difference of up to 500mm. The gripping tip is designed as a resiliently extendable anti-collision probe structure, integrating a pressure sensor and a miniature electromagnetic triggering device. When the probe 2231 encounters abnormal resistance during insertion into the pallet hole, a rebound mechanism can be triggered within 5–10ms to avoid mechanical damage. Simultaneously, an error code is sent to the control device, such as error type: hole misalignment, foreign object blockage, pallet deformation, etc. The system adjusts the gripping strategy or suspends operation in real time accordingly.

[0044] Specifically, a high-precision electronic level (±0.1° accuracy), monitoring device 227, is built into the center of the gripper to monitor the pitch and roll angles of the pallet in real time after gripping. Combined with inertial measurement units (IMUs) and vision sensors installed at the robot joints, the system can construct a dynamic model of the pallet's posture. When the material pallet is detected to be in a critical stable state, the robot (industrial manipulator) automatically reduces its acceleration and adjusts the gripping force distribution through a closed-loop control algorithm. Testing has shown that this mechanism can reduce the probability of pallet slippage to below 0.5% even under high-speed robot movement (maximum speed 2.5 m / s), while improving average operating efficiency by approximately 25% compared to traditional gripping systems.

[0045] Specifically, an eccentric wheel vibration motor (polarization mechanism 226) is integrated at the connection between the gripper and the robot flange. This module is driven by a brushless DC motor, and the vibration frequency and amplitude can be adjusted within the range of 50–200Hz via a program. After unloading, the system initiates a short-duration (typically 0.5–2 seconds) vibration mode, using high-frequency micro-amplitude vibrations to break the adhesion between the powder and the tray surface, effectively solving the problem of residue from fine particulate materials (such as flour, cement, and plastic powder). The vibration parameters can be adaptively learned and matched by the host computer according to the material characteristics.

[0046] It should be noted that this invention completely abandons pipeline conveying technologies such as spiral feeding or pneumatic conveying, and uses a large robot to directly pick up the raw material pallet and pour the powdered raw material directly into the dispensing device, thereby fundamentally solving the problems of high failure rate caused by changes in raw material composition and the principle of conveying device.

[0047] It should be noted that because this invention uses a robot (industrial robotic arm) to directly pour the raw material pallet, it eliminates the high failure rate problem of the feeding device in the prior art. However, the new structure is still susceptible to failure. To reduce the equipment failure rate, this invention adds multiple sensors based on structural innovation, all of which are dual-sensor backups, effectively reducing the equipment failure rate. The main sensors involved in this invention are as follows: First, the raw material pallet transfer rack is equipped with a proximity switch sensor to detect the arrival status of the raw material pallet. The proximity sensor is a magnetic sensor that can detect the magnetism of the pallet's metal.

[0048] Second, a laser sensor is added to the end effector of the robot's 6 axes to detect the positioning of the gripper and the pallet. If a positioning deviation occurs, the robot will not operate to prevent damage to the robot or the pallet. This sensor is a laser positioning sensor used to detect the presence or absence of the gripper.

[0049] Third, the dustproof opening of the material storage box is equipped with a position sensor to detect the opening's open / closed state and prevent the tray from colliding with the storage box. The position sensor is a magnetic sensor that can detect the magnetism of the tray's metal. Fourth, a position sensor is installed inside the storage box to prevent overfilling. The position sensor is a magnetic sensor that can detect the magnetism of the metal tray. Fifth, the material box tray conveying module is equipped with a laser beam sensor to detect the position of the material box tray and determine whether it is offset.

[0050] In addition to employing a robot-assisted direct material pouring method, this invention significantly improves the uniformity of raw materials within the storage box due to the large area of ​​the pallets and their high rotation and tilting speed. Furthermore, by using a counting method, odd-numbered pallets are rotated and tilted clockwise and counterclockwise respectively, thereby maximizing the uniformity of raw materials within the storage box.

[0051] This solution uses a servo-controlled double-speed chain conveyor system. Through the absolute encoder technology built into the servo system, the precise positioning of the material box pallet on the conveyor device can be achieved.

[0052] The intelligent packaging system for brake shoe raw materials in this invention has the following characteristics: 1. The raw materials for the quantitative dispensing device are replenished by a robot direct material feeding device (i.e., robot conveying module, etc.).

[0053] II. The three-pronged gripper of the robot's transport module and the design of the raw material pallet module, using an insert-type mating method.

[0054] 3. In the method of direct material pouring by robot, odd-numbered pallets and even-numbered pallets are tilted clockwise and counterclockwise respectively to maximize the uniformity of raw materials in the storage box.

[0055] IV. The precise positioning of the material box tray is achieved through a servo-controlled double-speed chain conveyor with a double-sided support structure.

[0056] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
